✓ Who Should Buy
- •Building managers and contractors requiring adjustable, controlled closing for standard interior or exterior doors.
- •Users seeking the convenience of an integrated hold-open feature for high-traffic areas or accessibility.
- •Installers looking for a non-handed, surface-mounted closer compatible with wood and metal doors.
- •Facilities needing a reliable door closer for doors within the 60kg / 950mm size 3 range, where fire rating is not a primary concern.
✕ Who Should Avoid
- •Applications requiring door closers with fire-rated certification (e.g., for fire-rated door assemblies).
- •Installations on doors exceeding 60kg or 950mm width, which would necessitate a higher power size closer.
- •Projects where specific international standards like EN1154 compliance are mandatory and explicitly required.
- •Users seeking advanced features such as back check or delayed action functionality.
Product Overview
The Godrej Dyna Door Closer Hold Open Size 3 represents a reliable hydraulic solution for surface-mounted door control, specifically designed for a broad range of applications on both wood and metal doors. Engineered with a durable Aluminium Alloy body and finished in PU/Silver, this model ensures long-term operational integrity. Its Size 3 power rating is meticulously calibrated for doors weighing up to 60 kilograms and extending up to 950mm in width, providing optimal control without excess force. A key feature is its non-handed design, which significantly simplifies specification and installation by eliminating the need for left or right-hand door orientation. Users benefit from precise control over door movement through independently adjustable closing and latching speeds, allowing for a customized closing sequence from the full 180-degree opening down to the final secure latch. The integrated hold-open function enhances user convenience, permitting the door to remain open when required. This unit has undergone rigorous testing, achieving a performance rating of 100,000 operational cycles, underscoring its durability. It comes complete with all necessary installation hardware and is backed by a 3-year manufacturer's warranty.

Engineering Analysis
The Godrej Dyna Door Closer Hold Open Size 3 is engineered around a robust hydraulic mechanism, utilizing precision-machined adjustable valves to govern the door's closing and latching speeds. This hydraulic principle ensures controlled fluid resistance, preventing uncontrolled door movement and mitigating potential impact damage. The adjustable closing speed allows for tailored door closure rates from the maximum opening angle of 180 degrees down to approximately 15 degrees, while the adjustable latching speed precisely controls the final few degrees of closure, ensuring secure engagement with the strike plate without slamming. Crucially, the integrated hold-open function, enabled by a dedicated arm assembly, offers user convenience by securing the door in an open position at a user-defined angle, facilitating unimpeded traffic flow or material handling. This functionality is distinct from back-check or delayed action features, which are not present in this model.
Constructed from a durable Aluminium Alloy body with a PU/Silver finish, the Dyna closer is designed for longevity, validated by a rigorous 100,000-cycle test rating, ensuring reliable performance over its 3-year warranty period. It is engineered for doors up to 60kg in weight and 950mm in width, aligning with its Size 3 power rating.
Regarding compliance, it is important to note that the Godrej Dyna Door Closer Hold Open Size 3 is not fire-rated and does not carry specific EN1154 certifications. This positions the unit as an effective solution for general-purpose, controlled access applications on wood and metal doors where fire safety requirements or stringent international standard adherence are not the primary drivers. Its non-handed design simplifies specification and installation, enhancing its versatility across various architectural layouts.
